About Us

Pediatric Cardiology Associates (PCA) specializes in the diagnosis and treatment of congenital and acquired heart disease for pediatric and adult patients. The most common type of pediatric heart disease is congenital heart disease (CHD), meaning that children are born with it. Congenital heart defects can exist in adults, but are still considered CHD if the adult was born with the disease.

Our focus is on the care of the fetus, newborn, child, adolescent and adult with congenital or suspected congenital and acquired heart disease. In some cases, congenital heart disease can be diagnosed before a baby is born. Six of our physicians have an expertise in fetal cardiology and imaging of the fetal heart and cardiovascular physiology.

We pride ourselves on clinical excellence provided in an atmosphere of compassion and trust. Take great care of the patient, every day and in every way, is our mission. We know that visiting a pediatric cardiologist for the first time can be stressful. Our dedicated staff helps patients feel comfortable by helping them understand the evaluation process as well as their plan of care. It is our goal to provide the best in cardiac care to our patients and educate their entire family.

In order to better serve our patients, we maintain multiple convenient clinic locations throughout the Virginia and Maryland area.

Inova Pediatric Vaccine Effort

Dear Pediatric Community,

Inova Children’s has been working diligently for the past several weeks in preparation for the impending approval by the Advisory Committee on Immunization Practices (ACIP) approved the Pfizer Covid-19 vaccination for children ages 5-11. These efforts have been a collaboration with state and local health departments, school system leadership and most importantly our state AAP leadership and pediatric partners within the community.

We know that in this region most parents intend to vaccinate their children—most as soon as they are able to do so—and almost every parent prefers to get their child vaccinated with their pediatrician or family doctor.

As part of broad, community-wide efforts to support the pediatric vaccination effort, Inova is hosting a series of child-friendly vaccine clinics at Inova Center for Personalized Health on weekends beginning November 6th by appointment only. Appointments are contingent upon vaccine availability.

These clinics will only offer the specific reconstitution of the vaccine for 5- to 11-year-old children; vaccine for ages 12 and up will not be available at these clinics.

We expect high demand in the first weeks of vaccine availability. In addition to Inova Children’s Vaccination Clinic at ICPH, there will be many options for children to receive the COVID-19 vaccine, including Community Vaccination Centers (CVCs), retail pharmacies, pop-up locations as a collaboration between the school systems and health departments, and of course pediatrician and family practice offices.

Please visit www.inova.org/vaccine for more details on how to make an appointment at the Inova Children’s Vaccination Clinic and for information on all the vaccination resources available in our community.

Finally, in addition to preparing for Inova-based vaccine efforts we have prepared a series of educational videos and print content that can be utilized within schools, private practices, by the health departments and any other organization interested in educating on why vaccination is critical to the health of our children and how to best prepare a child for the vaccine.

Thank you for all of your combined efforts to help our children.

Should my child get the Covid Vaccine?

Our physicians are ​recommending the COVID vaccine for our age-appropriate patients, but ultimately it is entirely up the parents/family if they would like to proceed with the COVID vaccine. Our physicians believe the benefits of the vaccine clearly outweigh the risks of any possible side effects from the vaccine. If you have specific questions or concerns regarding the vaccine, you should contact your pediatrician or family physician. If the pediatrician/family physician has any specific concerns, they can reach out to us directly.

  • Dr. Sharon Karr and Dr. Sarah Chambers specialize in the evaluation and management of the fetal heart during pregnancy.

IAC accreditation = Care you can count on
